Trying to enable plugin in final 2.80 under Ubuntu 19.04. Getting this error:

Cycles and system see's my GPU with no problem. GPU - Titan RTX.

Edited: Lol, my library just called "libOpenImageDenoise.so" without ".0" at the end. So I made a soft link with that name and now it is loading.

Likewise here but without the libOpenCL.so.1 part.

[...]

Weird because that libs are really present.

I guess what you need is to install the OpenCL library in your system.

For doing that in Ubuntu 19.04:

sudo apt install ocl-icd-libopencl1

[shrisha]

Thanks, will try that.

Creating symlink helped to load RPR. But it is crashing when trying to render something. Investigating further.

[shrisha]

creating symlink and installing ocl-icd-libopencl1 package solved this issue.

Thanks.  We'll fix the installer.
